Thanks for playing! I used the FastNoiseLight using cellular and changed the settings a bit, used a color ramp to get the green and blackish colors set and set it to seamless and saved it as a PNG. Then I used the parallax2d to repeat it, because when I tried using the noise to generate the background on the fly, it dropped the FPS like crazy. Originally, I had planned on using just random bits of grass, but when I was looking around, I found that it might be hard for red/green color blind folks to see the monsters if the background was mostly solid green, so I opted for the cellular setting to give it some patterns. *edit: I pasted an image on another response, because I hadn't realized I could add it to the existing comment hah...
